OWNERS' WALL
It looks fantastic in person and rides even better than expected — very responsive, sharp handling, and feels quick as soon as you put the power down.
Douglas Chrystall, ER:ONE ULTEGRA ownerVERIFIED
This bike far exceeds my expectations. It is very neatly detailed. The paint is flawless… all of my rider friends are jealous of this bike and it's incredible value.
Craig, ER:ONE ULTEGRA ownerVERIFIED
1kg lighter than my Scott Foil… once up to speed, it is truly aero. Price-quality ratio is definitely worth it; a top bike for much less money than a major brand.
Werner Van Looy, ER:ONE ULTEGRA ownerVERIFIED
Amazing bike, support was great from the team and shipping arrived without problems to Australia.
